T0 all whom'ifi ma concern: V

.Be it known that I, FRANK BERNARD some; of the town of; Trige rso'll, in the county of @Xford, in the Province of Om tario, Canada, have invented certain new and useful Iinprovements in Hearing Guards, of which thefollowing' is the speclfieation.

My invention relates to improvements in apple coring machines, and the object of the invention is to devise a revdlving' holder for' the apple which will not be detrimentally affected by the" fruit juice entering the bearing-s and it consists essentiallyof a sup porting" base. a rotatable. proiig carrying spindle, hearings carried by the supper-ting base in which the spindle is j ournaled and ceihprising a member carried by the shaft and members car-r d by the base such mend hers ctr-acting te at to form closed b in adapted reassure the entrance of juice hetweeii bearing surfaces of such bearing,- as hereinafter more particularly explained by the following specification. 1,

Figure 1 is a perspective view of my holder. Fig. 2, is longitudinal section through the holder.

in the drawings like letters of reference indicate corresponding parts in each figure.

A is a base portion forming part of the main frame of the coring machine.

A and A -are reversibly set main cups forming part of the base A and provided with central alined orifices A and A*.

B an d B are felt washers fitting into the cups A and A each having a central orifice B registering with the orifices A and A of the cups.

C is a spindle carrying the usual prong end (1 designed to be inserted in the apple. The spindle C is provided with a reduced portion (1 extending through the orifices A and A* of the cups. The reduced portion C is provided with threaded portions C and C.

D and D are bearing cups fitting into the cups A and A against the washers B B located in each cup A and A The cups D and D are provided with threaded central orifices D to allow of the cups being inserted onto the threaded portions C and G I E and E are ball bearings located in the cups 1) and D.

it and .F are bearing cause which are mg, and packing means inserted there;

threaded upon the threaded portions C? and C against the halls. .The cones F, and F are provided with annular flanges F and F fitting into the. cups A and A G and G are felt rings which fit into the cups A and A against the outer. edges of the bearing cups D and D and against which the inner face of the flanges F and F of the cones F and F. bear.

H is a lock nut which is threaded onto the threaded portion U against the outer cone F.

I is a driving gear al'so threaded and secured onto the threaded portion C of the spindle C. p

In assembling my device, the inner cone is threaded upon the threaded portion 0*, a'felt' was-her G is then placed into position against the flange F The washer B" is then" inserted into the cup ,AQ The cup D is then insert'ecl into the cup A. against the washer B and the spindle C slipped through the orifices A? ar id A so that the threaded portion C projects through the cup A The felt vashel-D is theninserted into the cup A and the cup D inserted againstthe felt washer, the baIlsLof the hearing are then placedinto position and a cone F carrying a felt washer G similar to the felt washer is threaded into the threaded por'tioii (1* of the'spindle against the ball bearings the lock nut H is then threaded into position.

I In apple corers which have hitherto been 1n use the spindle has been rotatably held in a bearing sleeve provided with a sleeve bushing open at the ends and allowing of the free entrance of the juices flowing from the cut fruit which gradually works into the bearing, eating into the metal, and gradually loosening the shaft therein. This has the effect of allowing the shaft to move out of center and to allow it to travel in a circular path around such center having the final effect of cutting a gradually increasing size of hole in the apple and wasting more and more of the apple. In addition to this it resulted in splitting the smaller and softer apples and causing the paring knife used in this class of machine which operates on the rotating surface of the apple to break the peeling thereby causing the knife to skip long circumferential strips of peeling which necessitated such strip being removed by hand thereby Wasting the fruit. It will also be seen that frequent renewals Were neeeasary that adding greatly to the operat-= ing expense of the machine. By my invention the juice is deflected radially by the member F forming the cone and away from the shaft, any small amount of juice which might pass between the members F'and A being stopped from further entrance to the bearing by the washer G and any which might enter between the shaft and member A by the washer B. Thus the bearings are thoroughly protected from detrimental effect of fruit juices and therefore, always remain in perfect axial alinement enabling the corer which is a-half round spoon to cut the same size core portion from the apple at all times. 1 am also enabled to peel a small and softer apple without splitting and yet allow the peeling knife to be set to take a thinner peeling thereby preventing wasting. 1 also provide a permanent bearing eliminating the necessity of renewals as in the case of the old style of sleeve bushing. The amount of power required to operate the machine is less and I also eliminate the troublesome feature of the coring spoon becoming engaged with the prongs of the apple holder while removing the core as with my construction the axis of the spindle is 7 always central.

' It will be seen from this description that I have provided a smooth running'apple holder into the bearings of which juice will be prevented from entering by means of the I washers G and B, G and 13 thus preventing the bearings being affected by the sticky or acid qualities of the juice.

Although in this description I have devised the bearings as ball bearings it will,

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,-

of course, be understood that they may be roller bearings. Again although I show an adjustable jam nut for the cone it will be understood that I might use a set screw extending through the cone against the spindle C, but these are mere details of construction. I desire to say however, that changes may be made in such details without departing from the spirit of my invention. It is necessary, however, that the bearings carrying the spindle C should have the bearing surfaces remote from the spindle thereby avoiding any liability of the acid juice passing along the spindle and into the bearings.

What I claim as my invention is.

In an apple paring and coring machine, a base, a cup having a central opening secured to the base, a bearing cup having a central opening mounted in the cup on the base, an absorbent packing washer having av central opening interposed between said bearing cup and the cup on the base, the openings in said bearing cup, washer and cup on the base being in alinement, a shaft extending through such alined openings, a bearing cone threaded upon said shaft and provided with an annular outstanding flange adapted to fit within the cup on said base, balls interposed between said bearing cup and cone, and an absorbent packing washer interposed between the outstanding flange of said hearing cone and the flange of said bearing cup.
